The world welcomed Mila Kunis and Ashton Kutcher's baby girl last September 30 at the Los Angeles' Cedars-Sinai and the pair couldn't be happier!

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world," the '2 And A Half Men' announced on October 2. "May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy."

Of course it wouldn't be Ashton Kutcher if there wasn't any punking involved.

He chose to introduce his daughter to the world via a guessing game.

The proud father even shared a photo of his daughter, Wyatt Isabelle - among other pictures of random babies.

"Can you guess which one is ours, or does it really matter?" he asked. "All babies are cute."

He posted eight photos - including a dog and a llama - for people to choose from, making the event a fun but frustrating one as well.

He also posted on Facebook, "Here's your baby photo. Well, one of them is. Now can the helicopter please stop hovering over our house, there is a baby sleeping inside! And she's super cute."

However, TMZ and US Weekly says they've figured out which one is the real Wyatt Isabelle - the first baby!

The first clue was reportedly the first baby's similar features with the 'That 70s Show' alums. Another clue was the blue and red stripped baby blanket and matching cap that Cedars-Sinai exclusively uses for newborns.

Fans have also started to figure out which one is the real Kunis-Kutcher baby. Most of them are torn between baby number one and the infant with the yellow hat!

"I'm either guessing the first one, looks like Mila or the one in the yellow hat sleeping, looks like Ashton," one fan commented.

Another fan pointed out, "The first one. Looks just like Mila!"

Which photo do you think is Ashton Kutcher's real baby? Do you agree with TMZ and US Weekly? Does baby number one really look like both parents?
